Abstract

We use Monte Carlo simulations of hard Gaussian overlap (HGO) particles symmetrically confined in slab geometry to investigate the role of particle-substrate interactions on liquid crystalline anchoring. Despite the restriction here to purely steric interactions and smooth substrates, a range of behaviors are captured, including tilted anchoring and homeotropic-planar bistability. These macroscopic behaviors are all achieved through appropriate tuning of the microscopics of the HGO-substrate interaction, based upon nonadditive descriptions for the HGO-substrate shape parameter.
